HANGING CIRCULJAR s ws.

srnorrroA rron forming part of Letters Patent No. 254,142, datedFebruary 28, 1882.

Application filed December 18, 1880. (No model.) Patented in GermanyOctober 8, 1880, in England November 30, 1880, in Franc December 15,1880, and in Austria February 19, 1881. e

To all whom 'it may concern:

Be it known that I, JACOB Krrz, of Neuschleussig, near Leipsic, in theEmpire of Germany, have invented anew and useful Improvement in CircularSaws, (for which I made application for Letters Patent in Germany on orabout the 6th day of October, 1880,) of which the following is aspecification.

The nature of my invention consists in arranging or securing thesaw-blade to a ring fitted over a hub securely attached to the axis,said ring being arranged to turn around suitable journals attached tothe hub and secured in any desired diagonal position by suitable screws,whereby a groove of any desired width may be cut into the wood accordingto the diagonal position of the ring and saw-blade to the axis.

In the accompanying drawings, Figure 1 represents a front view of acircular saw embodying my invention. Fig. 2 is a cross-section of thesame. Fig. 3 is a horizontal section, showing the saw-blade square tothe axis; and Fig. 4 is a horizontal section, showing the saw-bladeplaced diagonal to the axis.

Similar letters represent similar parts in all the figures.

A is the axis, upon which a hub, B, is firmly attached. This hub isprovided with two pro- 0 jecting pins or journals, 0 O, opposite eachother.

D is a ring made in two parts, between which the saw-blade E is firmlysecured, and

provided with suitable holes, into which the round the pins or journals.The two halves forming the ring D are secured together by suitablescrews, 1).

On one side of the ring D a lug or projection, F, is provided at rightangles to the center line of the journals 0, through which a suitablescrew,G,passes,screwinginto the hub B, by means of which the diagonalposition of the ring D and saw-blade E can be regulated.

J J are set-screws, arranged to act against the pins or journals 0 O, oragainst their surrounding brasses, to secure and fasten the ring andsaw-blade in the desired position.

Whenever the saw-blade is secured square to the driving-axis, as shownin Fig. 3, the groove cut into the wood will be of a width correspondingwith the thickness of the sawblade in the usual'manner.

When a wider groove should be desired, the

saw-blade is secured,-in the manner above described, diagonal to theaxis A, as shown-in Fig. 4, when the width of the groove to be out intothe wood will depend upon the diagonal position of the saw-blade inrelation with the axis A.

What I claim as my invention, and desire to secure by Letters Patent,is-

In combination with a hub, B, firmly secured to adriving-shat't, A, andprovided with projecting pins or journals 0 G, the ring D, with sawblade E, the screw G, and set-screws J J, constructed and arranged tooperate in the manner and for the purpose substantially as described.
